Max is bitten by a rattlesnake while on a camping trip. His friends immediately apply ice packs to the bitten area to slow the spread of the protein-based toxin; they then rush him to an emergency facility. Upon doing blood work, it was determined that Max had a bacterial infection from a tick bite resulting in a primary humoral response.  The doctor told Max that he was lucky because the tick could have also caused Lyme's disease, but he had natural active immunity to that microbe.

Explain why Max did not also get Lyme's disease. What role did his immune system play in preventing this infectious disease?
